To Aoclllwkam t may concern.' i

Y Be it known that I, HUGH M. ROCKWELL,

; a citizen of the TJnited States, residing in Vthe cityof Bristoh'county of Hartford, and

5' State lof Connecticut, have invented a new Lband useful Improvementin a Belt-Loading Machine, of which the Vfollowing specification is .such a clear and exact description as to lenable one skilled in the art to which it l1Q` appertains to make and-use the same.

, .This invention relates to a device for assembling cartridges and links'to form a belt vofthe disintegrating type. Devices of thisf character comprise a bed j', lhaving'means for positioningV a plurality of cartridges andvlinks in assembling relation,

means for .preventing movement of the links vand apusher bar for simultaneously forcing the cartridges into the links and means for i v operating the pusher bar.l It is the object vof 'this vinvention to improve generally upon these devices and to'provide a machine which ishighly eflicient in' operation.

An additional object is to provide. means whereby the path of travel of the pusher bar may be changed withoutvarying `the length ofthe path'. This object is attained by proi 1 viding an adjustable connection between 's Y,

' 35 inthe vmode of connecting the operating means to the bed. Brackets, having vertical slots, are arranged at either endof the bed and anl operating bail is provided with Vrollers on `its ends toengage in said slots.

i' 40 lThe ends .of the pusher bar are journalled in the ends of thebail and horizontal guides for the pusher bar are arranged on the bed. This arrangement produces a sturdy structure 'which Vallows applying the necessary pressure to the operating means withoutv danger ofaff'ecting the eiicient operation of the device. Y

Other objects and features ofthe invention will be apparent from the following.

specification and accompanying claims. p

Referring now to the drawings: f Fig.' 1 is a perspectiveview of my device;

Fig. 2 is a side elevation thereof;

Fig. 3 isa detail'of a lever. l

The device comprises a bed 1 having grooves'2 on the upper surface, one side of said bed :having stops or lugs 3 forming the U shaped spa-ces 4f. At either end of the bed, spaced therefrom and near the rear edge part of the operating thereof, areA the brackets 5 provided' with. the slots 6, the lower ends of which are open. Y

Carried by the ends of the bed are'the guide plates 7 in which are provided the slots 8, closed at each end, but which exceed. in length the throw of the pusher bar tobe later described. Y

The operating lever 9 is'bail shaped and has forked or divided ends comprising the two arms 10 and 11. Extending through the' slots 6 and joining the arms 1Y0 and 11 are'k the pins 12 on which are mounted the rollers 13. Set in the arms 10 are the eccentric;Y

bushings 14 which are held against rotation by the set screw 15. Journalled in these bushings are the ends of the pusher bar 16.

Inusing this device the links L are placed in the grooves 2 as shown in Fig. 1 and then the cartridges Care also laid in the-grooves but to the rear of the links and inspected. I have shown only a-few of the links and cartridges in place but in practice the' whole bed is filled. Before this is done the operating lever hasv been moved so that the pusher bar is in its rearmost position. The operating lever is then thrown forward until it has assumed a'horizontal position.- Thelever pivots around theend's of the pusher bar and the rollers 13 move down and upl in the slots 6 causing the pusher bar which is held against vertical movement by the sides of the slots 8 to be moved forwardly. The forward movement of the` pusher bar forces the cartridges into the links which are prevented from moving forward by virtue of the stops 3. When the lever has assumed a horizontal position7 the pusher bar has been advanced the full extent of its throw and has forced the cartridges into place in the links forming a belt of limited length. The operating lever is then returned to its initial position, the belt and cartridges picked up and moved along and the end link is placed in the last groove after which the operation is repeated.

After considerable usage, the thickness of the stops 31s decreased and the cartridges coinpanying elainis.Y

- sition' in would not he forced fai enough into links. Adjustment -Of the @eeen trie hushinff 14 is then mede to throw the'pusher hai" foi*- Waicl enough to compensate for JChis weer.

Thus if; seen that I have provided simple end eilioient heli; loading machine which combines Wih simplicity of consten@- tion and opeioion, e. high degree O eilieieney. Y
